MySQL schema migration safety reviewer and DDL generator. ALWAYS use when writing, reviewing, or planning MySQL schema changes — ALTER TABLE, CREATE/DROP INDEX, column type changes, charset conversions, data backfills, or any DDL touching production tables. Covers online DDL algorithm selection (INSTANT/INPLACE/COPY), lock-safety analysis, large-table migration with gh-ost/pt-osc, phased rollout design, replication-safe DDL, backward compatibility, and rollback planning. Use even for "simple" ADD COLUMN — MySQL DDL locking behavior is version- and operation-dependent, and mistakes cause production outages.
